An instant poll of debate spectators shows a slight preference for President Barack Obama in tonight’s second presidential debate at Hofstra University in Hempstead, New York.

The poll, which consisted of 33 percent Democrats and 33 percent Republicans, showed 46 percent of viewers thought Obama won compared to 39 percent for Romney. Twelve percent thought the debate was a tie.

Though the poll of people who watched the debate indicates a solid advantage for Obama, it is within the 4.5 percent margin of error.

A CBS News poll shows a similar margin of victory, with 37 percent of viewers saying the president won compared to 30 percent who though Romney won, but those results also are within the 4 percent margin of error. Thirty-three percent of viewers in that poll viewed the debate as a tie.
